Hey everybody, I was gone for a long time from here. My bettas are all doing great.
Just one problem: One of them gets SO stressed when I move him out of his tank for cleaning. I usually put him in a cup while I clean and he turns really pale. Then I started noticing when I put him back into his tank his color immediately comes back but a few hours later his fins are all shredded. I don't think it has anything to do with decorations because when his fins grow back they stay that way until it's time for cleaning again.
What can I do to avoid this problem from always happening?
